    Makefile: allow building without perl · 499c2939
    Jeff King authored
    For systems with a missing or broken perl, it is nicer to
    explicitly say "we don't want perl" because:
      1. The Makefile knows not to bother with Perl-ish things
         like Git.pm.
      2. We can print a more user-friendly error message
         than "foo is not a git command" or whatever the broken
         perl might barf
      3. Test scripts that require perl can mark themselves and
         such and be skipped
    This patch implements parts (1) and (2). The perl/
    subdirectory is skipped entirely, gitweb is not built, and
    any git commands which rely on perl will print a
    human-readable message and exit with an error code.
    This patch is based on one from Robin H. Johnson.
